We are using Audio extender card with BF-533 Ez-Kit Lite. We are receving digital data through ADAV801 and SPOrt0.
This data is transmitting through AD1938 on Sport1.
We have provided 0-db sine tone as input, Then in the output we have observed -12db difference in amplitue level. When we check in Sport1Tx buffer, we found 0x7FFF000, means no attenuation in the receiver. So, problem can be in ADAV1938.
Anybody is having idea whether AD1938 will provide any attenuation.
